Freedom High School grad Daniel Dae Kim, star of "Hawaii Five-O,' has been making the rounds on the east coast, making appearances at a White House dinner with Prime Minister of Japan Yoshihiko Noda hosted by Secretary of State Hillary Clinton on April 30, attending the White House Correspondents Dinner on Saturday and appearing on "Live! WIth Kelly" this morning in New York City.

Kim talked with Kelly and guest cohost Pat Kiernan about the dinners, his sons and about "Hawaii Five-0's" two-part crossover event with "NCIS: Los Angeles," which concludes tonight at 9 p.m. on CBS.

Kim, who has taken a spotlight role with Scott Caan, is featured prominently in the episodes. Kim said the plot is about "a bad guy who has decided to weaponize smallpox."

"It's a laugh a minute," he joked.

In the crossover, investigators from "NCIS: Los Angeles," including star Chris O'Donnell, come to Hawaii to help the "Hawaii Five-O" team solve the crime.

"Run DDK, run!" exlaimed Kelly.

Said Kim, "I'm just trying to keep up with LL Cool J. I'm like a 12-year-old boy standing next to him."

Kim has become chums with Kelly since co-hosting with her in February when the show aired live from Hawaii, where he lives.

"Welcome home," Kelly said, as she greeted him.

They talked about the White House Correspondent's dinner, before which Kim asked fans in a tweet if he should wear a bow tie or a neck tie.

He picked a neck tie.

"The president is debating whether to kill a terrorist and I'm debating about whether to wear a bow or a neck tie," Kim said, self-deprecatingly.

Talking about the White House dinner with the Japanese prime minister, Kim remarked how he is fascinated about how politicians can put on a friendly public face "at the same time there's a Chinese dissident seeking asylum in the Chinese embassy." He was referring to Clinton, who is dealing with a crisis regarding blind dissident Chen Guangcheng, who sought refuge in the American embassy in Bejing.

"It's a pretty fascinating study in human nature," he said.

Kim also talked a little about his two sons, one who is a tennis player and competing in a championship match this weekend. Kim said he was sad he would miss it.
